Abstract

The invention discloses a method for improving soil by rice field-upland field rotation of leaf vegetables and aquatic vegetables, and relates to the field of agricultural planting. The method comprises the following steps: step 1, performing planting of aquatic vegetables in a dry land where xerophyte crops are planted for a long time from July to December in Hainan, performing planting of a season of leaf vegetables after planting a season of aquatic vegetables in the same year, and repeating the steps for three times, wherein complete random block arrangement is adopted for each planting. The aquatic vegetables comprise watercress, cress, water spinach and watercress. The leaf vegetables comprise flowering cabbages, Chinese cabbages and pakchoi cabbages, the EC value, the pH value, theanion content and the cation content of plough layer soil are all improved through the method, and the improvement effect is obvious.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a method for improving soil by paddy and dry rotation of leaf vegetables and aquatic vegetables and a detection method thereof. Background technique [0002] In recent years, unreasonable industrial and agricultural activities have led to the accumulation of heavy metals in a considerable number of vegetable soils in my country, among which the problem of excessive cadmium (Cd) content is more prominent. Cd is a heavy metal element with high bioavailability, strong accumulation and high toxicity. Compared with other heavy metals, Cd is more easily absorbed by crops, especially leafy vegetables, and is one of the most important heavy metal pollution elements in leafy vegetables. Leafy vegetables are the type of vegetables with the largest amount of daily consumption. Cd enters and accumulates in the human body through the food chain, posing a potential threat to human health. ...
